\ sPEcIFIc'A'I'grON. TO ALL WHOM IT MAY CONCERN Be it known that I,ANDREW P. ODHOLM, of Bridgeport, in the county of Fairfield, and Stateof Connecticut, have invented a new and improved Machine'for Dressingthe FelloesofWheels;` and I do'hereby declare that the following is afull, clear, and exact description thereof, which will enable thoseskilled in `the art` to make and use the same, reference being had totheaccompanying drawings, forming part of this specilication, in whichtFigure 1, sheet No, v1, is afront sectional 'view of my invention, takenin the line z z, fig. 2.

This invention relates to a new and improved machine for dressing'thesides of the felloes of wheels, and is more especially designed foroperating upon carriage-wheels. The object of the invention is to obtaina machine of simple construction which willadmit of the work beingrapidly and perfectly performed, and capable of being adjusted tosuit'wheels of di'erent sizes or diameters.

A represents a framing, which may be constructed in any proper manner,to support the working `parts ot the machine, and` havinga'semicircularhorizontal platform,B, upon it, through which aver-tical arbor or shaft,C, passes, the lower end of said arbor or shaft being stepped in a bar,a, of the framing, 4as shown at Vb, and the upper bearing in a bar, c,underneath the platform B, (see fig.- 2.) 0n the upper .part o f thisarbor, C, above the platform B, there is secured a cutter, D,constructed of a series of serrated circular plates or small circularsaws placed one above the other. vThis cutter, however, maybeconstructediu any proper way-anygkind which 'will'make a smooth cut willanswer the purposef--and I therefore do not confine myself to anyparticular con-` struction of cutter. In one of the tophorizontal'barsd, of the framing, A, there is made a longitudialslot, e,in which a slide, D*, is fitted and allowed to move or work freely. Thisslidehas a vertical arbor, E, fitted in it by means of a screw-thread,f, cut on its lower part, so that by turning the arbor it may be raisedor lowered and adjusted .to the desired height, the Aarbor just abovethe .screw having a `fixed serrated or milled thumb-wheel, g, upon itfor the convenience of -tturning it, and-also to serve as a bearing forthe hub of the wheelto boperated upon,las shown in red in lig. 2. In theupper surface of the platform thereis litted a horizontal metallic Y tplate, F, which isr adjusted by a screw, G, shown in figs. 2 and 3, saidplate being provided with a semicircular bow portion, h, as shown iniig. `3, so that it may not in its adjustment interfere with the arboror shaft C and cutter D. The plate Fis provided with two pendent ears orlugs i z', which'serve as' bearings for asruall shaft, j, on which a hubor boss, k, is keyed or otherwise secured, said hub or boss beingprovidedwith a series of radial arms, l, at equal distances apart, whicha'rms work through a slot, m, in the plate F, and' project a suitabledistance above tlie upper surface of the same. The hub or boss k has aseries of lteeth, n, made in it near one end, and H is a lpawl whichengages with said teeth and prevents the hubpr boss and its arms fromcasually turning. This pawl is formed `with a spring tang, '0, or has aspring connepted with or applied to it in such a manner as to keep thepawl engaged with the teeth n, (see ig.4,) and a portion of the pawlprojects upward through a slot in plate F to admit of it being depressedat the proper time in order to become disengaged from the teeth n andadmit of the arms l being turned. n 4

The parts above des'cribed, with the exception of Vthe cutter, refertothose which are used for dressing the outer edgesof the felloes onwhich the tire is fitted, and this side or surface of the felloes isdressed in a` plane parallel with the axis of the wheel. The wheel isplaced on the arbor E in"`sl`ide D*, the end of the hub resting on thethumb-wheel g, the arbor E being raised or lowered so that one side ofthe felloes may rest -on the plate F, and the plate F adjusted so thatthe arms'l may be in contact with the inner` side or surface of thefelloes, and the outer side or surface.be in contact with the cutter D.The arbor E is lthen 'rotated by any conv/enient power, and the wheel isturned by hand, so that' the cutter D will dressl'oii` the outer edgesor surfaces of the felloes. The arm l of the hub or boss c, whichprojects up through` theplate F, serves as a guide to keep the outeredges lor surfaces of the felloes in contact with'the cutter; and eachspoke of ythe wheel, as the latter is turned, presses down the pawl H asthe spokes come in contact with the part which projects up through plateF, and

this depression of the pawl sets the hub or boss k at liberty and allowsthe spoke which depressed the pawl to turn the arm l down out of the wayso that it may move along, and a succeeding arm l is turned up throughthe ,plate F at the rear of the spoke above. mentioned. Thus the armsare prevented from interfering with the movement of the spokes as thewheelis turned, each spoke before it comes in contact with' the arm Z,which is acting as a guide to the wheel, elevating the hub o r boss fromwhich the arms project, so that the spoke may turn the arm down, passover it and raise another arm at. its rear, which arm is turned down bythe succeedingspoke, and so von-it beingiinderstood, of course, thatthe'pawl H' engages with a tooth, n, of the hub. or boss each time anarm reaches a vertical position at the inner sides of the felloes. Thesides of thel felloes are dressed as follows: The hub'of the wheel istted on an arbor, I, which projects from a slide, J, fitted in apendant, K. This pendant is suspended by a rod, p, from a slide, L,which worksV between horizontal guides, M M, attached to an' upright, N,secured to the framing A, the slide L being secured at any desired pointwithin the scope of its movement by a 'pin, 'g. The swinging movement ofthe pendant, K, admits of*` the sides of the felloes being adjustedtothe cutter D either in a vertical or in an inclined plane, and thisadjustment of the wheel to eect this result is accomplished by a plate,O, attached to the plate F, and provided withan upright lip, r, whichbears against the sides of lthe `felloes opposite to the' sides againstwhich; the cutter D acts, (see {ig.'2.) By adjusting the plate F throughthemedium of the screw G, the-lip r will, 'in connection withV theadjustment of the slide L, incline the wheel more or less or retain itin a vertical position. The outer sides or surfaces of the y {'ellcesare dressed in a vertical plane at right angles with the axis of thewheel, but the inner surfaces are dressed in aninclined planecorresponding with'v the plane in which the spokes of the Wheel areplaced, moet wheels being deishedf' as it is technically termed, by'incliningthe spokes in a greater or less degree.

'Ihis invention has 4recently beenput in practical operation, and itperforms its work well, trueing the wheel perfectly, and giving it aneat and finished appearance. v I In the drawings the swinging-pendantK, arm I, and other apparatus for supporting the wheel where the back ofthe felloe is being pressed, are supported by 4an upright fromtheframing, A. They may, however, be arranged by connecting them with theside of the room overthe machine;k and I will ordinarily arrange them inthis way.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- 1. TheiuslideD, with adjustable arbor E attached; therotary vcutter D, and the adjustable plate F, provided with the guidearms Z, arranged so as to rotate, as shown, 'or in any other equivalentway, to admit of I being removed or adjusted out of the way of thespokes by the action of the spokes themselves-in the turning of thewheel, substantially as and for the purpose s et forth.

v 2. The swingingfpendant; K, suspended from the adjustable slide L,having an arm, I, attached, in connection with the plate O, on slideFand the cutter D, all arranged to operate substantially inthe manner asand for the purpose specitied. V l
